Hymek
The British Rail Class 35 is a class of mixed-traffic B-B diesel locomotive with hydraulic transmission. Because of their Mekydro-design hydraulic transmission units, the locomotives became known as the Hymeks. They were numbered D7000-D7100. The class was developed for the Western Region of British Railways, which had opted for lightweight locomotives with hydraulic transmission, when allocated funds under the British Railways Modernisation Plan of 1955. 101 of the class were built between 1961 and 1964, when it became apparent that there was a requirement for a medium-power diesel-hydraulic design for both secondary passenger work and freight duties. They were allocated to Bristol Bath Road, Cardiff Canton, and Old Oak Common. None of the class was named. Withdrawal from service began in 1971, and was completed by 1975. Their early withdrawal was caused, primarily, by BR classifying the hydraulic transmission as non-standard. Development The builder, Beyer Peacock (Hyme ...

Beyer, Peacock And Company
Beyer, Peacock and Company was an English railway locomotive manufacturer with a factory in Openshaw, Manchester. Founded by Charles Beyer, Richard Peacock and Henry Robertson, it traded from 1854 until 1966. The company exported locomotives, and machine tools to service them, throughout the world. Founders German-born Charles Beyer had undertaken engineering training related to cotton milling in Dresden before moving to England in 1831 aged 21. He secured employment as a draughtsman at Sharp, Roberts and Company's Atlas works in central Manchester, which manufactured cotton mill machinery and had just started building locomotives for the Liverpool and Manchester Railway. There he was mentored by head engineer and prolific inventor of cotton mill machinery, Richard Roberts. By the time he resigned 22 years later he was well established as the company's head engineer; he had been involved in producing more than 600 locomotives. Richard Peacock had been chief engineer of the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Region Of British Railways
The Western Region was a region of British Railways from 1948. The region ceased to be an operating unit in its own right on completion of the "Organising for Quality" initiative on 6 April 1992. The Region consisted principally of ex- Great Western Railway lines, minus certain lines west of Birmingham, which were transferred to the London Midland Region in 1963 and with the addition of all former Southern Railway routes west of Exeter, which were subsequently rationalised. History When British Railways was created at the start of 1948, it was immediately subdivided into six Regions, largely based upon pre-nationalisation ownership. The Western Region initially consisted of the former Great Western Railway system, totalling 3,782 route miles and with its headquarters at Paddington. To this was added some minor railways and joint lines in which the GWR had an interest: *Brynmawr and Western Valleys Railway *Clifton Extension Railway * Easton and Church Hope Railway *Great ...

British Rail Class 52
The British Rail Class 52 is a class of 74 Type 4 diesel-hydraulic locomotives built for the Western Region of British Railways between 1961 and 1964. All were given two-word names, the first word being "''Western''" and thus the type became known as ''Westerns''. They were also known as ''Wizzos'' and ''Thousands''. Historical context When switching to diesel traction as part of the Modernisation Plan of the 1950s, British Railways (BR) designed, and commissioned designs for, a large number of locomotive types. At this time BR's regions had a high degree of autonomy, which extended as far as classes of locomotives ordered and even the design criteria for those locomotives. Whilst almost all other diesel locomotives were diesel-electric, the Western Region employed a policy of using diesel-hydraulic traction, originally commissioning three classes of main line locomotives: a type 2 and two type 4s (later designations Class 22, Class 41 and Class 42). With pressure to incr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Torque Converter
A torque converter is a type of fluid coupling that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. It is usually located between the engine's flexplate and the transmission. The equivalent location in a manual transmission would be the mechanical clutch. The main characteristic of a torque converter is its ability to increase torque when the output rotational speed is so low that it allows the fluid coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a reduction gear. This is a feature beyond that of the simple fluid coupling, which can match rotational speed but does not multiply torque and thus reduces power. Hydraulic systems By far the most common form of torque converter in automobile transmissions is the hydr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rail Blue
The history of British Rail's corporate liveries is quite complex. Although from the mid-1960s to the 1980s the organisation was associated with "Rail Blue", a number of other schemes were also used, especially when it was split into operating units or "sectors" in the mid-1980s. Pre-corporate liveries At the formation of British Railways on 1 January 1948, early diesel and electric locos and the gas turbine locomotives 18000 and 18100 were already painted black with aluminium trim, but by the late 1950s this had been superseded by the same shade of green that was used on express passenger steam locomotives, although some locomotives were painted in a two-tone Brunswick and Sherwood green livery, and Southern Region electric locomotives were painted a light shade of malachite green. Multiple units were also generally green, although this tended to be a lighter and bluer shade compared to the colour used on steam and diesel locomotives. Corridor coaching stock was originally t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laira Traction & Rolling Stock Maintenance Depot
Laira T&RSMD is a railway traction and rolling stock maintenance depot situated in Plymouth, Devon, England. The depot is operated by Great Western Railway and is mainly concerned with the overhaul and daily servicing of their fleet of High Speed Trains and also the DMUs used on local services. The depot code "LA" is used to identify rolling stock based there. After sixty years as a steam depot, servicing locomotives used on the Exeter to Plymouth line that runs past the shed as well as local lines, diesels started to arrive in 1958. A diesel depot opened in 1962 and was expanded in 1981 to accommodate the High Speed Trains. History Steam shed Laira was the location of the temporary terminus of the South Devon Railway from 5 May 1848 when a small engine shed would have been provided. With the completion of the line to Plymouth Millbay railway station on 2 April 1849 a new shed was provided there and the facilities at Laira dismantled, although it remained a junction for ...

Newton Abbot Engine Shed
Newton Abbot railway station serves the town of Newton Abbot in Devon, England. It is from London, measured from the zero point at to the junction for the branch to . The station today is managed by Great Western Railway, who provide train services along with CrossCountry. For many years, it was also the junction for the branch line to Moretonhampstead and the site of a large locomotive workshop. History Broad gauge The station was opened by the South Devon Railway Company on 30 December 1846 when its line was extended from Teignmouth railway station. It was opened through to on 20 June 1847 and a branch to Torquay was added on 18 December 1848. The Moretonhampstead and South Devon Railway opened its branch line on 26 June 1866. All these railways used the broad gauge. Approaching the station from the town along Queen Street, people first saw the large goods shed. On the opposite side of the line was the pumping house for the atmospheric railway system that powered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiff Canton TMD
Cardiff Canton TMD ( cy, Depo Cynnal a Chadw Treganna Caerdydd) is a diesel locomotive traction maintenance depot in Cardiff, Wales. Its depot code is CF. It is operated by Transport for Wales. The depot is used by Transport for Wales fleet and some Cross Country Class 170s. In steam days the depot was called Cardiff Canton and its shed code was 86C. It was built in 1882 as the main maintenance base for the South Wales Railway and the major Welsh engineering base for the Great Western Railway (GWR). After nationalisation in 1948 it was a heavy overhaul base for British Railways. After privatisation in the mid-1990s the depot became a joint Arriva Trains Wales and English Welsh & Scottish facility. The EWS depot closed as a maintenance centre from 10 December 2005, but EWS' successor DB Cargo UK still uses the depot for long-term storage and occasional stabling. History Steam Cardiff Canton was opened in June 1882 as a six road, -long shed, built to replace Long Dyke, ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Oak Common TMD
Old Oak Common TMD was a traction maintenance depot located west of Paddington railway station, London Paddington, in Old Oak Common. The depot was the main facility for the storage and servicing of locomotives and multiple-units from Paddington railway station, Paddington. The depot codes were OC for the diesel depot and OO for the carriage shed. In steam days the List of British Railways shed codes, shed code was 81A. The area is also where two Great Western Railway main lines divide: the 1838 route to via , and the 1906 "New North Main Line" (present-day Acton–Northolt line) via to South Ruislip station, Northolt Junction, the start of the Great Western and Great Central Joint Railway line. The former is in use for regular passenger services; the latter is used overwhelmingly by freight trains and empty coaching stock movements. The 'HST' section of Old Oak Common TMD, more commonly known as 'Old Oak Common HST Depot' closed in 2018 with the removal of the InterCity 125s ...

Ian Allan Publishing
Ian Allan Publishing was an English publisher, established in 1942, which specialised in transport books. It was founded by Ian Allan. In 1942 Ian Allan, then working in the public relations department for the Southern Railway at Waterloo station, decided he could deal with many of the requests he received about rolling stock by collecting the information into a book. The result was his first book, ''ABC of Southern Locomotives''. This proved to be a success, contributing to the emergence of trainspotting as a popular hobby in the UK, and leading to the formation of the company.Ian Allan…the man who launched a million locospotters ''The Railway Magazine'' issue 1174 February 1999 pages 20-27 The company grew from a small producer of books for train enthusiasts and spotters to a large transport publisher. Each year it published books covering subjects such as military and civil aviation, naval and maritime topics, buses, trams, trolleybuses and steam railways, including hi ...
